Over the past decade, US Food and Allison miller escort Administration FDA -approved immune checkpoint inhibitors that target programmed death-1 PD-1 have demonstrated significant clinical benefit particularly in patients with PD-L1 expressing tumors. Toripalimab is a humanized anti-PD-1 antibody, approved by FDA for first-line treatment of nasopharyngeal carcinoma in combination with chemotherapy. In a post hoc analysis of phase 3 studies, toripalimab in combination with chemotherapy improved overall survival irrespective of PD-L1 status in nasopharyngeal carcinoma JUPITERadvanced non-small cell lung cancer CHOICE and advanced esophageal squamous cell carcinoma JUPITER On further characterization, we allison miller escort that toripalimab is molecularly and functionally differentiated from pembrolizumab, an anti-PD-1 mAb approved previously for treating a wide spectrum of tumors. Toripalimab, which binds the FG loop of PD-1, has fold higher binding affinity to PD-1 than pembrolizumab and promotes significantly more Th1- and myeloid-derived inflammatory cytokine responses in healthy human PBMCs in vitro. Additionally, binding of toripalimab to PD-1 induced lower levels of SHP1 and SHP2 recruitment, the negative regulators of T cell activation, in Jurkat T cells ectopically expressing PD Taken together, these data demonstrate that toripalimab is a potent anti-PD-1 antibody with high affinity PD-1 binding, strong functional attributes and demonstrated clinical activity that encourage its continued clinical investigation in several types of cancer. Immune checkpoint inhibitors ICIs targeting programmed cell death 1 PD-1 and programmed cell death ligand 1 PD-L1 have revolutionized cancer treatment in the recent years, affording long-term survival benefit allison miller escort a broad range of cancer patients. PD-1 is an inhibitory cell surface receptor that is upregulated upon T cell activation. While this mechanism of regulating T cell immune response is necessary in maintaining immune tolerance to autoantigens, several tumors over-express PD-L1 in response to inflammatory mediators and downregulate anti-tumor function of T cells leading to tumor immune evasion [ 345 ]. In the allison miller escort years, the US Food and Drug Administration FDA has allison miller escort several anti-PD-1 monoclonal antibodies Abs that include pembrolizumab, nivolumab and cemipilimab for use in more than 50 tumor indications [ 7 ]. These PD-1 Abs have a beneficial effect on the treatment of patients with a broad range of advanced or metastatic cancer compared to conventional chemotherapy [ 8 ]. In most clinical studies, the PD-L1 status of the tumor correlated with the overall clinical benefit of the PD-1 therapy, whereby PD-L1 positive patients responded better to PD-1 immunotherapy treatment, either alone or in combination with chemotherapy. Similarly, the therapeutic efficacy of nivolumab correlated with the expression levels of PD-L1 in cancer patients CheckMate: ; PD-L1 screen: pharmDx assay [ 101112 ]. Furthermore, based on the objective response rate, PD-L1 high NSCLC patients gain more benefits than PD-L1 low patients in response to treatment with cemiplimab in combination with chemotherapy EMPOWER-Lung 3; PD-L1 screen: 22C3 pharmDx assay [ 13 ]. A similar benefit in the overall population upon treatment with atezolizumab was driven by patients with high PD-L1 expression IMpower PD-L1 screen: 22C3 pharmDx assay [ 14 ]. Thus, there is an unmet need for PD-1 treatment approaches that clinically benefits cancer patients irrespective of their PD-L1 status. Toripalimab is a PD-1 targeting humanized IgG4 monoclonal Ab that has been recently approved in combination with cisplatin and gemcitabine by US Food and Drug Administration FDA for the first-line treatment of adults with metastatic or recurrent locally advanced nasopharyngeal carcinoma NPCand as monotherapy for the treatment of adults with recurrent, unresectable or metastatic NPC with disease progression on or after platinum-containing chemotherapy. Considering that prospective clinical studies with appropriate power are required to evaluate the efficacy of toripalimab in the PD-L1 subgroup, we evaluated with these preclinical studies if there are pharmacological parameters of toripalimab that could further support such studies. Pembrolizumab which is approved in the largest number of tumor indications in the PD-1 Ab class and has provided clinical benefit in various solid tumors was used a comparator [ 15 ]. Three randomized controlled phase 3 studies with toripalimab plus chemotherapy were evaluated for overall survival OS stratified by PD-L1 levels. Two PD-L1 scoring criteria, tumor proportion score TPS and the combined positive score CPSwere used for post hoc analysis. The JUPITER study Fig. The hazard ratios HR for the PD-L1 high and low subgroups are 0. Toripalimab in combination with chemotherapy improved overall survival in a post hoc analysis of randomized controlled trials. Numbers of patients at risk at indicated time points are shown below the x axis. Number of events, median OS, hazard ratio for death and nominal p values are shown in the table below the Kaplan—Meier curves. CPS, combined positive score; ESCC, esophageal squamous cell carcinoma; HR, hazard ratio; NE, not estimated; NSCLC, non-small cell lung cancer: NPC, nasopharyngeal carcinoma; OS, overall survival; PD-L1, programmed cell death ligand 1; TPS, tumor proportion score. The CHOICE study [ 1617 ] Fig. The JUPITER study[ 18 ] Fig. To evaluate the binding kinetics of toripalimab to human PD-1, surface plasmon resonance SPR assay was performed with the toripalimab immobilized on C1 sensor chips. The human PD-1 protein was flowed across the PD-1 Ab at various concentrations. Biacore sensograms of PD-1 binding to covalently immobilized toripalimab Fig. S1 A were compared to pembrolizumab Fig. Since we observed a very slow dissociation of PD-1 from toripalimab, more extensive dissociation data were generated for toripalimab with additional injections at the highest antigen concentration followed by a longer dissociation phase Fig. Toripalimab showed fold higher affinity for PD-1 compared to pembrolizumab, 0. The association rate constant k adissociation rate constant k d and equilibrium dissociation constant K D for pembrolizumab and toripalimab are listed in Fig. The higher binding affinity of toripalimab is explained by its dissociation rate constant k d that is fold slower than pembrolizumab, 2. Together, these data demonstrate that toripalimab shows significant differences compared to pembrolizumab in its binding kinetics and affinity to human PD Representative SPR analysis of human PD-1 binding to PD-1 antibodies. A Biacore sensorgrams of PD-1 binding to covalently allison miller escort toripalimab. PD-1 was injected in triplicate for 3 min in a range from 0.

Stable synapse formation at the T cell—APC conjugation is required for T cell activation and is regulated by the accumulation of PD-1 at the immunological synapse [ 33 , 34 ]. These data suggest that toripalimab has increased potency to activate CD8 T cells even in the absence of PD-L1 expressing APCs or tumor cells.
